airflow control for unoccupied zone

There are various demands for air-conditioning in each office space resulting from the variability of thermal distribution caused by a bias of heat sources. Furthermore, individual demands on the thermal environment are diverse. Therefore, it is difficult to satisfy all demands using conventional air-conditioning systems since these assume perfect mixing. Instead, demand may vary with the result that some spaces could be excessively or unnecessarily cooled. This paper examines an airflow and temperature control for personal air-conditioning.
